So, I was wondering how to make a sprite do things based off what another sprite does. Specifically, I need 4 sprites to change their costume when 1 sprite's costume is changed. These 4 sprites are hidden, and when they are cloned with W, A, S, or D, they are shown.

When the controlling sprite changes costume it sends a broadcast message.

broadcast [Change costume now v]

The other four sprites receive it and change their costumes.

when I receive [Change costume now v]

Thanks. And is there any way for a sprite to sense what costume it's already been?

You mean, not what costume it is now, but what it once was?

You just need to use the computer memory, that's all. Create a variable called LAST COSTUME and update it as needed.

Thanks! This really helped. Project's almost done.

is there any way to make you not be able to switch a sprite's costume if it's already been that costume?

Yes. One way is to use the use the IF/THEN block.

However, if what you want to do is have a list of costumes and then randomly select them until they have all been used, then using a LIST variable would be the way to go. Put all your costume names in the list. Choose them randomly and then each time you choose one, delete it from the list.

I need someone to be able to choose which costume to change to, but if one was already used, I want to make it unavailable. I tried this:

ask [which costume? a=X, b=Y, c=Z, etc] and wait
if <(answer) = [a b c d or e, depending on what costume]> then
switch costume to [stuff v]
wait (1) secs
change [the corresponding variable v] by (1)
end
if <<(answer) = [whatever letter]> and <(corresponding variable) = [1]>> then
say [something to the effect of no] for (2) secs
ask [the same question as the first one] and wait
end
but even if the costume wasn't picked before, it won't let you pick it.

You are misunderstanding the answer block. All it is is the exact thing they type into it. So in your example the only answers that would trigger anything would be…
a b c d or e, depending on what costume
or…
whatever letter

And you are also misusing the ask block since it is also literal. If you ask “the same question as the first one” then that's what will appear on the screen …
The same question as the first one?

Just use:

if <([costume# v] of [Sprite1 v]) = [1]> then
...
end

100th post!

Can you post a link to the project? It might be easier for everyone to help you that way.
